Abstract:

The purpose of this research was to determine the capabilities of two different microwave scanning technologies. This research focuses on each systems ability to detect the presence of defects within materials consisting of Lexan or Nylon. The defects for this evaluation consist of four inline holes of known diameter and varying depth across a dielectric plate. Special consideration was given to the each systems ability to dimension the plate defects accurately with repeatability. It was found that the XY Table Scanner and Handheld Scanner are both capable of detecting the induced defects in the Lexan and Nylon plate. It was concluded that the XY Table Scanner is a better system for increased accuracy in dimensioning with a percent error range of 44.452 to 94.899 compared to a range of 191.713 to 338.693 for the Handheld Scanner. The XY Table was also shown to produces higher quality images and was easier to use than the Handheld Scanner. However, it was also found that neither scanning technology was capable of determining the depth of surface or sub-surface defects.
